BigXwell Solar Pool Cover, 12Mil 16x32 Foot Rectangle for Ab
✅ PROS
- 12-mil thickness provides noticeably better tear resistance than the bargain 8-mil covers, surviving wind gusts and pool toy snags
- Bubble cells trap heat effectively; multiple buyers report 5-8°F water temperature gains after a few sunny days
- Cut to true 16x32 dimensions with a slight overlap allowance, so it covers the water surface edge-to-edge without gaps
❌ CONS
- No reel or storage system included — you'll need to buy one separately or wrestle this wet, heavy cover manually
- UV degradation is real; expect a 2-3 season lifespan in full-sun climates before the bubbles start flattening
The Verdict
Let’s be blunt: most solar pool covers under $100 are glorified trash bags. They tear the first time you drag them across a rough pool edge, they don’t actually warm the water, and they disintegrate by August. The BigXwell 12Mil is not that cover — but it’s also not a miracle product. Here’s the honest breakdown.
What You Actually Get
The box contains a single blue, bubble-wrapped rectangular sheet measuring 16x32 feet. At 12 mils, this is the thicker end of the residential spectrum — most budget covers are 8 mils, and the difference is immediately obvious when you handle it. The bubbles are the standard 1-inch diameter cells you expect on solar covers. There’s no grommets, no tie-downs, no straps. It’s just the sheet. If you have a rectangular above-ground pool with a 16x32 footprint, this will cover it with a few inches of overhang on each side, which is exactly what you want to keep debris out and heat in.
Real-World Performance
The primary job of any solar cover is heat retention, and this one does it. The bubble cells act as a greenhouse — they let sunlight through to warm the water while trapping that heat against the surface at night. Multiple buyers report water temperature increases of 5-8°F over a few days of consistent sun, which is the difference between a “refreshing” dip and a “nope, too cold” one.
The 12-mil thickness matters more than you’d think. Thinner covers ripple in the wind, catch on ladder rails, and tear at the first sign of stress. This one has enough heft to lay flat and resist moderate wind gusts. One reviewer noted, “Survived two thunderstorms without blowing off or tearing — my old 8-mil wouldn’t have made it through one.” That tracks.
What Buyers Praise
The recurring theme in the 215 ratings (4.3 stars) is the value-to-thickness ratio. Shoppers specifically call out that they paid more for thinner covers that didn’t last half a season. As one verified purchase put it, “This is the third cover I’ve bought in two years. The first two were cheap and fell apart. This one actually feels like it’ll make it through the season.” Another buyer appreciated the true-to-size cut: “Fits my 16x32 pool perfectly with a little overlap — no gaps at the corners.”
Where It Falls Short
No cover is perfect, and the BigXwell has two honest drawbacks.
First, there’s no reel system. At 16x32 feet, this cover weighs roughly 25-30 pounds when dry and significantly more when wet. You’ll need to either buy a separate solar cover reel (another $60-100) or accept the awkward, water-spilling dance of dragging it off by hand. If you’re not physically up for that, factor a reel into your budget.
Second, UV degradation is inevitable. The bubbles will flatten and the material will become brittle after 2-3 seasons in full sun. That’s normal for any solar cover, but the 12-mil thickness doesn’t make it immortal — it just means it lasts longer than the cheap alternatives. If you live in Arizona or Texas, expect a shorter lifespan than someone in the Pacific Northwest.
Who Should Buy This
This is for the above-ground pool owner who wants to extend their swim season without spending $200+ on a cover. It’s ideal for:
- Budget-conscious families who want 80% of the performance of premium covers at half the price
- DIY pool maintainers who already have a reel or don’t mind manual removal
- Anyone replacing a thin, torn cover who’s tired of buying replacements every year
Skip it if you have an in-ground pool with a custom shape (this is rectangular only), or if you want a cover with integrated straps and hardware — you’ll need to buy those separately.
FAQ
Will this work on an in-ground pool? Technically yes, if your pool is a 16x32 rectangle. But the cover is designed for above-ground pools, so the edges won’t have the reinforcement needed for heavy in-ground use. Buy a pool-specific cover for inground.
How long does it take to heat the water? Expect 3-5 days of full sun to see a noticeable difference. It’s not instant, and it works best when you keep the cover on whenever the pool isn’t in use.
Does it keep leaves and bugs out? Yes, while it’s on. But you’ll need to remove it to swim, and anything that lands on top will slide off or sit there until you pull the cover.
The Verdict
Buy it if: You want a genuinely thicker, more durable solar cover that actually raises water temperature, and you’re okay with buying a reel separately or handling it manually.
Skip it if: You need a cover with included hardware, have a non-rectangular pool, or live in extreme sun where you want a UV-stabilized premium cover.
The BigXwell 12Mil delivers exactly what it promises — a solid, true-to-size solar cover at a fair price. It won’t change your life, but it will change your pool’s temperature. At 4.2/5, it’s one of the better values in this category.
